What is the difference between thorax and chest?
The thorax is also called the chest and contains the main organs of respiration and circulation. The heart through its main artery, the aorta, pumps oxygenated blood to all parts of the body.
What are different types of Macrotrichiae found in insects?
The various types of microtrichia are simplified as binding and thorn-like shapes. The model was established based on three sections: the VS of the elytron, hindwings and abdomen. The second section (hindwing) is more complex because it changes during the folding process.
What are the types of thorax?
The middle tagma, or thorax, comprises three large segments: prothorax (anterior most segment), mesothorax (middle), and metathorax (posterior) (Figure 33.3). Each segment contains chitinous plates, or sclerites, which provide support and some protection.
What is in an insect’s thorax?
The thorax is the midsection (tagma) of the insect body. It holds the head, legs, wings and abdomen. It is formed by the prothorax, mesothorax and metathorax and comprises the scutellum; the cervix, a membrane that separates the head from the thorax; and the pleuron, a lateral sclerite of the thorax.
What is the major function of the thorax cage?
The thoracic cage, like skeletal tissue in most parts of the body, serves to support the thorax. It also has several functions, such as: protecticting vital thoracic and abdominal internal organs from external forces.
What are the different types of insect head orientation?
TYPES OF INSECT HEADS.
Why do insects have varying types of antennae legs and mouthparts?
Insects are all related, they share a common ancestor at the base of their family tree. From this ancestor all insects inherited a basic anatomy and body plan. The diversity in form, and ultimately function, found in insects is a result of changes made to basic anatomical elements such as legs or mouthparts.
What are the three segments of thorax?
The insect thorax consists of three segments (called the prothorax, mesothorax, and metathorax), which may be fused but are usually recognizable.
What are the three segments in an insect’s thorax?
The thorax consists of three segments called the pro-, meso-, and metathorax. Appendages used for movement are attached to the thorax. Each of the segments of the thorax bears one pair of legs and if wings are present they are found on the meso- and metathorax only. The top of the prothorax is called the pronotum.
What is the most important function of thorax?
But it’s also where we get most of the rotation of our trunk. So if you like running, golf, swimming, walking, tennis, football, or almost any physical activity, you need good function in your thorax. The nerves from our thorax supply the abdominal muscles; these muscles protect our lower back and abdominal organs.
